AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
700 AM CDT FRI JUN 11 2010

.UPDATE...
RAIN HAS PUSHED EAST OF I-29 CORRIDOR AND SHOULD EXIT EASTERN PARTS
OF THE CWA BY 15Z. CANCELLED REMAINDER OF THE SEVERE THUNDERSTORM
WATCH...AS WELL AS WESTERN PORTIONS OF THE FLASH FLOOD WATCH EARLY.
SOME ADJUSTMENTS TO TIMING OF FLASH FLOOD WATCH EAST OF A YANKTON TO
SIOUX FALLS LINE TO COVER POTENTIAL FOR LOCALLY HEAVY RAIN IN SERN
PARTS OF THE CWA THROUGH THIS EVENING. UPDATED GRIDS AND ZFP HAVE
BEEN SENT.

&&

.DISCUSSION...
WELL DEFINED BOW ECHO PRODUCING REPORTS OF 65-75 MPH WINDS SHOULD BE
EXITING EASTERN PARTS OF THE AREA IN THE NEXT HOUR OR SO. BROAD AREA
OF MORE STRATIFORM RAIN WITH SOME EMBEDDED THUNDER EXTENDING OVER
THE REMAINDER OF THE CWA AS OF 09Z...WITH BACK EDGE LIFTING
NORTHEAST THROUGH EASTERN NEBRASKA AS WEAK WAVE MOVES THROUGH
SOUTHWEST FLOW ALOFT. EXPECT MUCH OF THIS ACTIVITY TO EXIT TO THE
EAST BY MID-LATE MORNING...AND TOUGH TO TELL WHERE LINGERING OUTFLOW
BOUNDARIES WILL SET UP FOR THE AFTERNOON...BUT BEST CONSENSUS FROM
MODELS PLACE THE MAIN BOUNDARY NEAR A KYKN-KFSD-KMML LINE BY LATE
AFTERNOON...PUSHING SOUTHEAST INTO NORTHWEST IOWA DURING THE EARLY
EVENING. ABILITY FOR CONVECTION TO REFIRE THIS AFTERNOON WILL DEPEND
TO SOME DEGREE ON EXTENT OF CLEARING/HEATING OUT ALONG AND AHEAD OF
THE BOUNDARY...THOUGH AIRMASS EXPECTED TO BE QUITE JUICY WITH LOWER
70S DEW POINTS LIKELY INTO NORTHWEST IOWA THIS AFTERNOON. HAVE
PUSHED BACK TIMING OF REDEVELOPMENT TO LATE AFTERNOON TO ALLOW A
LITTLE MORE TIME FOR HEATING/DESTABILIZATION...WITH GREATER CHANCE
OVER NORTHWEST IOWA THIS EVENING AS ANOTHER WEAK WAVE LIFTS
NORTHEAST ACROSS THE BOUNDARY. HAVE CONTINUED FLASH FLOOD WATCHES
FOR NOW...BUT WILL LIKELY BE ABLE TO CANCEL SOUTH DAKOTA COUNTIES A
FEW HOURS EARLY AS RAIN BEGINS TO LIFT OUT OF THE AREA PRIOR TO 12Z.
WILL CONTINUE FLASH FLOOD WATCH FOR NWRN IA/SWRN MN TO COVER
POSSIBLE REDEVELOPMENT IN THE AFTERNOON...AS DEEP MOISTURE WILL
AGAIN BRING POTENTIAL FOR LOCALLY HEAVY RAINFALL.

LITTLE CHANGE TO REMAINDER OF THE FORECAST SATURDAY THROUGH TUESDAY.
PERIODIC RAIN CHANCES AS WEAK WAVES MOVE OUT OF THE MAIN TROUGH THRU
SATURDAY NIGHT...FOLLOWED BY SOME UPPER RIDGING WHICH SHOULD KEEP
THE LATTER HALF OF THE WEEKEND DRY MOST AREAS. MAIN TROUGH EXPECTED
TO LIFT NORTHEAST INTO THE NORTHERN PLAINS EARLY NEXT WEEK...AND
WILL STICK WITH HIGH CHANCE POPS FOR NOW LATE SUNDAY NIGHT THROUGH
MONDAY NIGHT.

&&

.AVIATION...
MVFR-LOCALLY IFR CIGS WITH BROAD AREA OF RAIN/TSRA EXPECTED TO
GRADUALLY LIFT INTO VFR RANGE AS UPPER WAVE LIFTS NORTHEAST AND
PUSHES RAIN EAST OF THE AREA BY 15Z. POTENTIAL FOR ADDITIONAL TSRA
ALONG/EAST OF A KYKN-KFSD-KMML LINE DEVELOPING MID-LATE AFTERNOON AS
ANOTHER UPPER WAVE LIFTS NORTHEAST ALONG LINGERING LOW LEVEL FRONT
ACROSS THE AREA. PERIODS OF MVFR-LOCALLY IFR CIGS/VSBYS WILL AGAIN
BE POSSIBLE WITH ANY TSRA LATE THIS AFTERNOON/TONIGHT...WITH
GREATEST CHANCE SOUTH OF I-90.
